Bluetooth on the GPD Pocked with Linux

I finally got bluetooth working on my GPD Pocket.

This is with Fedora 26 and the rawhide kernel, but it probably works with many other kernels.

/sys/kernel/debug/usb/devices tells me the bt chip is a Broadcom Corp BCM2045A0

I thought this would need special firmware etc, but that's not the case or the firmware is already available on Fedora.

The issue here is the weird USB id: 0000:0000

To get it working:
# modprobe btusb
# echo "0000 0000" > /sys/bus/usb/drivers/btusb/new_id

To make this permanent (On Fedora 26):
Save this to /etc/rc.d/rc.local:
#!/bin/bash
modprobe btusb
echo "0000 0000" > /sys/bus/usb/drivers/btusb/new_id

exit 0
 
And then:
# chmod 755 /etc/rc.d/rc.local
# systemctl enable rc-local
